Interesting.. I switched over to a tank of different
juice last night (AV Gorilla
juice) & did a side-by-side comparison of the foam to a ceramic wick with similar resistance on the same equipment. For some reason, with the new
juice, I agree with others that the flavors with the foam are muted to a degree. Its interesting that with the previous juice (heavy citrus flavors), it tasted fine, but with this juice, all the subtleties seem to be missing...tastes pretty bland in comparison to the same juice with the ceramic wick.
I also noticed that it really wasn't wicking as well as I thought it was...It delivers juice VERY quickly if you tilt it (which I just do out of habit), but I don't think its actually wicking as well as the ceramic. If I tilt it horizontally, the wick gets wet very fast, the vapor increases tremendously, and it has a little more flavor....but still not as good as with the ceramic. I also noticed that when the wick dries out, you really don't get a dry-hit - its more of a "soft hit"...not as noticeable as with other materials...it kind of just peters out. I almost wonder if the cleaning process affected it in some way, but its the same way I always clean my coils (rinsed in warm water & dry-burned till the coils glow bright red a few times until the gunk burns off). Just kind of odd.
So, I'm left with some mixed feelings at this point. I still think it works better than the Stainless Steel wicks, but I've been using ceramic wicks (or Ekowool in my Oddys/Ithakas) for the last few months so I'm only going from memory. I guess a true test would be to roll up a Stainless wick & do a three-way comparo (I have three RSSTs)... its all subjective anyway, but it might be an interesting test.
For me personally, the foam hasn't displaced the ceramics - especially the White Wicks, but if you like Stainless or silica/hemp/cotton wicks, it's worth a try. I'll keep playing with it though...maybe a hybrid with another material might make it better - I have some more Ekowool in different diameters coming from Stormy's, so I might play with that later...
I still find it a fascinating material to play with....the answer may just be coming up with a different way to make wicks from it.
